Between version 2.87.0 and version 2.88.0, the hash calculation used to make sure that fn.currentVersion is automatically updated when a new version of the Lambda Function is deployed changed.

This causes a creation of a new Version upon upgrading CDK, but that new Version creation will fail because the underlying Function hasn't changed.

The change was due to property ordering used in calculating a unique hash for the Function configuration.

This change restores the property ordering to the pre-2.88.0 behavior.

Fixes #26739.
